Dost know what does the other end of the pipe?
Why, we have inserted it into the great rainwater tank yonder above our heads, which our grandsire contrived, and which is fed from the roofs and battlements of all the towers.

Thou hast heard our father tell how he read of such things in days of old, when men built wondrous palaces, and had hanging gardens, and I know not what beside.

He set the tank up there, and, as thou knowest, it is not now greatly used, albeit there is always water there, and at times men draw it forth.

It may not be the best or purest, but it will serve for washing, and for drinking too were a man in a great strait.

It is all pure and sweet now; for in the thunderstorm three nights since Bertram got up and let off all the stagnant water by the pipe which can be opened below, and the rain soon filled it again, it poured down with such goodwill.
